You should be able to write a relatively simple C language extension
that would let you do this. The interface to extensions isn't all that
hard to work with. It would probably be pretty useful for some kinds
of intensive crunching. There's one thing to watch out for: Intel
CPU's are going to a model where dynamically generated code won't
work unless you provide the correct incantation. This is to eliminate a
large class of viri.
